Iestyn Harris thought he had seen the back of Twickenham after ending his four-year stint in Welsh rugby union, but the Bradford stand-off has now set his sights on a return.

Harris, who captained Leeds to victory in the last Challenge Cup final at Wembley in 1999, led the Bulls to a 23-12 win against the holders Hull at Odsal on Saturday, setting up crucial tries for Marcus Bai and Shontayne Hape at the start of the second half.

Hull have lost six of their last seven matches, but their coach John Kear praised the battling performance of a team missing the injured forwards Richard Swain and Shayne McMenemy.

Catalans Dragons will be the only overseas team in tomorrow night's fifth-round draw after a 66-0 win against Thornhill on Saturday. Toulouse's dream of repeating last year's unlikely run to the semi finals was shattered with a 46-6 defeat at Harlequins, their first win at The Stoop this season.
